ROLLER WINDOW-SCREEN.

Specification of Letters Patent.

Patented Feb. 6, 1912..

. Application filed July 5, 1910. Serial No. 570,286.

To all whom it may concern;

Be it known that I, CHAnLns K. JENKINS,

a citizen of the United States, residing at.

fication.

This invention relates to improvements in roller window screen constructions of a type wherein the roller is stationarily positioned at one end of the window frame and is attached to one end of the screen, the other end of the screen being secured to a bar which is hung from or otherwise connected to one of the sashes, so that the winding or unwinding of the screen is consequent to a movement of the sash with which the said bar is associated.

According to the present invention the roller is partially inclosed in a casing and is of the ordinary spring wound type, its end trunnions being fitted in brackets which are of special construction for purposes which will hereinafter appear. The casing is also of special construction in order that it may beefl'iciently assembled indifferent positions, the brackets referred to being utilized in such assemblage.

.The invention is illustrated in the accompanying drawings wherein Figures 1, 2 and 3 are sectional views showingthe screen in use and showing alsothree different operative positions of the roller and its casing; Fig. 4 is a detail per spective View of the casing aforesaid, the roller appearing in dissociated relation; Fig. :5 is a detail sectional view of the roller casing; Fig. 6 is a detail perspective view of the bar to which one end of the screen is at tached; Fig. 7 is a detail perspective view of a friction shoe to be specifically described; and Fig. 8 is a detail front elevation of the roller casing in its assembled relation.

Similar characters of reference designate corresponding parts throughout the several views.

, mei'it is a plicable to -winclow consul.

sliding sas ment thereof.

The screen per 86 consists, as usual, of a sheet of flexible open-mesh material of any desired character, 6. 9. wire fabric or fancy net panels, and its ends are permanently secured to a transverse spring wound roller, as 5, of ordinary construction, and to a transverse bar, as 6, which is associated with one of the sash'es. The trunnions 7 of the roller 5 are fitted in brackets 8 and these are in turn secured to a casing 9. The latter, as shown in Fig. 1, is of L shape in cross section, comprising a vertical wall 10 and a horizontal wall 11 to which, at the ends thereof, the brackets 8 are secured. Said brackets, as shown in Fig. 4, are each provided at one end with a flange, as 12, for attachment to the wall 11, and at the other end with inwardly projecting apertured lugs, as 18. The brackets are also provided with horizontal slots 14 which receive the trunnions 7, one of the slots having an open end to provide for the ready removal and replacement of the roller in the usual manner.

Fig. 1 shows the screen mounted on the outside, adjacent the lower sash, in which case the bar 6 is secured to the lower rail of the sash 1, being for this purpose provided with hanger brackets 15 which have keyhole slots through which studs or pins provided on said lower rail may project, as hangers for the bar 6. In the outside use of the screen the casing 9 should be positioned slightly above the sill, as shown',.in order that a clearance may be afforded through which rain water may flow. In order to hold the casing 9 in this position, friction shoes are preferably employed, these being provided atthe ends of the casing, as shown in Fig. 4, and being preferably of rubber. One shoe, as 16, is stationary and the other, as 17 is movable. The construction of the movable shoe is shown in Fig. 7', wherein said shoe appears as carried by a block 18, which slides axially through a barrel, as 19. The barrel 19 is attached to the wall 11 and carries acam lever, as 20,'which is associated with the block 18 to produce the move- Fig. 2 shows the screen mounted on the inside adjacent the upper sash, in which case the casing is inverted as shown and is fastened by the shoes 16 and :17 described. It will be observed that the wall ll. is recessed at its forward corners and that the wall 10 is coextensive with that portion of the wall 11 which extends between the corner recesses. The walls 10 and 11 are thus formed in order that the projecting end portions of the wall 11 may fit into the grooves cle-- fined by the heads 3 and the inner molding strips, the latter fitting intojthe corner recesses aforesaid. In like manner when the casing is fitted as in Fig. 1 the corner recesses accommodate the outer facing strips as is obvious.

Fig. 3 shows the screen mounted on the inside at the lower portionofthe window.

In this case the wall 11 is of greater width.

- the latter of course being held in its upperwire and have inturned end most posit-ion.

To promote the efficient action of the screen, guides, as 23, are provided at the.

ends of the wall 11, as shown in Fig. eh

Theguides 23 are preferably constructed of ortions to engage over the edges of the abric composing the screen. Said fabric as it is led from the roller, is passed through the guides and the latter maintains the proper relation thereof, causing the fabric to travel evenly and without-crowding to one side or the other, or without becoming wrinkled as it is wound upon the roller. The guides also cause the roller to move forwardly as the diameter of the fabric roll diminishes, consequent to the unwinding thereof, the slots 14 providingfor such forward movement, as is dbvious. It follows that the bending movements of the fabric are easy and gradual and consequently the action of the device is rendered highly eficient and the life of the fabric prolonged.

In many instances it may be desired to have the operation of the screen independent of the raising and lowering of a sash. For this purpose the bar 6 may be provided with friction shoes 24 and 25 which are similar in construction to the shoes 16 and 17 respecout regard to the position of either of the sashes.

As shown in Fig. 6, the shoe 25 is p0- sitioned on the under side of the bar 6 and is accessible from the inside when the screen is disposed as in Fig. 1. But when the screen is disposed as in Fig. 2, itis neces'=' 7 sary to change the position of the shoe, the latter being then secured upon the for ward side of the bar 6, as is obvious. If

y when the screen is disposed, as in Fig. 2, the

bar 6 is to be associated with the upper rail of the lower sash, the brackets 15 are turned on their fastening screws from the position position of said brackets when the screen is disposed as in Fig. 1, to the position shown in dotted lines, and are secured by screws to the upper rail of the sash 2. When the screen is disposed as in Fig. 3, the fastening shoe 17 is generally not employed but if it is desired, for any reason, to use said shoe. the same is positioned upon the then u pcr face of the wall 11 and in advance 0 the roller.

From the foregoing description it will be apparent that the screen is applicable for use in any desired position, the necessary changes being oi inconse uential character and being easily and quick y made; and the action of the arrangement is of the most 'efiicient characten.

Having fully described my invention, I claim: I

1n a roller window screen an L shaped casing including a vertical and a horizontal wall, a roller and a section of screen fabric connected thereto, brackets secured at the ends of thehorizontal wall and in which the trunnions of the roller are journaled, the brackets being arranged adjacent the vertical wall and having inturned apertured lugsattheir free ends, friction shoes carried 'by the casing at the ends thereof for engagement with the adjacent faces of the window frame and a transverse bar secured to the free edge portion of the screen fabric, the bar having brackets whereby it may be attached to a sash rail.

In testimony whereof I have hereunto setmy hand in presence of two subscribing witnesses.
